SPOOL-HOLDER FOR SEWING -MACHINES.

SPECIFICATION forming part of Letters Patent No. 752,043,dated February16, 1904.

Application filed October 18, 1902. Serial No. 127,375.

To all whom it may concern:

Be it known that I, GEORGE W. COUGHEN- OUR, a citizen of the UnitedStates, residing at Norfolk, in the county of Norfolk, State ofVirginia, have invented certain new and useful Improvements inSpool-Holders; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to spool-holders for sewing-machines; and it hasfor its object to provide a construction, including a threadguide,wherein the thread from the spool will be unwound while the spool ispermitted to remain stationary, thus insuring against excessiveunwinding of the thread and consequent tangling.

Other objects and advantages of the invention will be understood fromthe following description.

In the drawings forming a portion of this.

invention, and in which like numerals of reference indicate similarparts in the several views, Figure 1 is a side elevation showing aportion of the arm of a sewing-machine equipped with a thread-holderembodying the present invention. Fig. 2 is a vertical section throughthe spool-holder, the arm of the machine being in elevation. Fig. 3 is asection online 3 3 of Fig. 2. Fig. 4 is a section on line 4t 4. of Fig.2. Fig. 5 is a detail perspective view of the slip-band on the lower endof the central or tubular core of the guide.

Referring now to the drawings, there is shown a portion of the arm 5 ofa sewingmachine, to which is secured the base-plate 6 of thespool-holder, said base-plate having a socket 7 at one end, in which isreceived the angular arm 8, comprising a vertical portion which isdirectly engaged with the socket, and an upper laterally-extendingportion, which latter terminates in a vertical sleeve 9. The bore of thesleeve 9 is greater at its upper end, as shown at 10, than at its lowerend, as shown at 11, and within the sleeve is disposed a tubular core12, having a circumscribing flange 13 at its upper end, said flangelying within and resting upon the bottom of the portion 10 of the bore,while the core below extending arm 14L, having (No model.)

the flange fits snugly but freely in the reduced portion of the bore andprojects from the lower end of the sleeve, as illustrated. The

core is thus free to rotate, but is held from dropping from the sleeve.At the low er end of the core 12 is alaterallya depending lug 15 at itsouter extremity provided with a perforation 16, the length of the arm14; being somewhat greater than the diameter of any spool that may beheld by the holder, the spool or thread, as illustrated, being disposedupon the stud 1'7 on the plate 6 and in aXial alinement with the sleeve9.

In the upper or enlarged portion of the bore of the sleeve 9 is looselyfitted a porcelain bushing 17, having a circumscribing flange 18, thatrests upon the upper end of the sleeve and holds the bushing with itslower end free from the upper end of the core 12.

In practice the thread from the spool is engaged in the eye orperforation 16, after which it is engaged or passed through the core 12and bushing 17'. To facilitate engagement of the thread in the core andbushing, said core and bushing are split longitudinally, so that thethread may be passed laterally into them, and no threading is required,the sleeve 9 being also split longitudinally, so that by bringing theslits of the core and bushing into registration with the slit of thesleeve the thread may be quickly engaged without removing the bushingand core from the sleeve. As the thread is drawn through the upper endof the bushing when the machine is operated the pull upon the lug at theouter end of the arm 14 is such as to cause the core to rotate, and thelug travels around the spool and unwinds the threadtherefrom instead ofthe spool rotating, as is usual. To prevent the thread from passingoutwardly through the longitudinal slit of the core as the latterrotates, a retaining-band 19 is employed and is engaged over the lowerend of the core. This retaining-band has a finger 2O struck uptherefrom, which may be grasped to place the band and remove it.retaining-band is split, and by pushing it around on the core its splitmay be brought into registry with that or the core and may be as easilymoved from registration.

The

IOO

It will be seen that with the present construction the arm of the corerotates to carry its lug around a spool and unwind the thread from thespool as it is required instead of rotating the spool, and to preventtoo speedy rotation of the core and the consequent possibility oftangling of the thread a set-screw 21 is engaged with the sleeve 9 andhas a felt or other yieldable end 22, which bears against the core, andby adjusting this screw the desired friction and consequent breakingeffect may be obtained.

Itwill be understood that in practice modifications of the specificconstruction shown may be made, and any suitable materials andproportions may be used for the various parts without departing from thespirit of the invention.

What is claimed is 1. A device of the class described comprising asleeve, provided with supporting means and a tubular core rotatablymounted in the sleeve and having a radiating arm having thread-receivingmeans at its outer end disposed for movement with the arm about a spoolwhen held in axial alinement with the core, and a bushing in the sleevebeyond the core, said bushing and core being adapted to receive thethread from the arm; the sleeve, the core and the bushing being slottedlongitudinally for registration of the slots of the core and bushingwith the slot of the sleeve at times.

2. A device of the class described comprising a sleeve, provided withsupporting means and a tubular core rotatably mounted in the sleeve andhaving a radiating arm beyond the sleeve having thread-receiving meansat its outer end and disposed for movement with the armabout a spoolwhen held in axial aline ment with the core, a bushing in the sleevebeyond the core, said bushing and core being adapted to receive thethread from the arm; the sleeve, the core and the bushing being slottedlongitudinally for registration of the slots of the core and bushingwith the slot of the sleeve at times, and a split ring sprung onto theouter end of the core and adapted for rotation thereon to open and closethe slot of the core.

In testimony whereof I afiix my signature in presence of two witnesses.
